All of the electronic interconnects that glue together the various components inside the logger box are now consolidated on a single printed circuit board. This should simplify ongoing maintenance and make it much simpler to produce additional loggers.

As an experiment, a diode and bleed resistor have been added to the battery charging port, which may help prevent galvanic corrosion at its terminals, which will almost certainly be exposed to some seawater.

We learned a number of lessons since the development of the first kite inflator PCB, including the need for a pressure release valve. The latest revision is much smaller overall, provides better electronic isolation of the pump motor, and more convenient positioning of connectors.
